MonoBand uses an on-device AI model to separate any track into vocals, drums, bass, guitar, piano, and more — so you can solo a single instrument, loop the chorus, change tempo without changing pitch, and record yourself on top. No internet. No subscription.
AI stem splitter, and more...
MonoBand is an iPhone, iPad, and Apple silicon Mac app that splits any song you own into 6 separate instrument tracks using Apple silicon — vocals, drums, bass, guitar, piano, and a catch-all "other" channel. From there it's a full studio: per-stem volume, solo/mute, a 3-band EQ and stereo pan on every channel, ±24-semitone transpose without changing tempo, speed change without changing pitch, A→B practice loops, bookmarks for verses and choruses, auto-detected BPM and key, AirPlay and Lock Screen control, and the ability to record up to 4 of your own takes over the song — with vocal effects (reverb, delay, compression and more) and non-destructive trim. Each channel shows its own waveform. It looks great in both Light and Dark mode. Everything runs locally — no servers, no account, no tracking.
Your songs, projects, and recordings sync across every device you own.
Built for musicians who want to learn songs note for note, producers who want stems for remixes, and anyone who just wants to sing over their favorite chorus.
Your device runs HT-Demucs on-device to split any song into vocals, drums, bass, guitar, piano, and other — in minutes.
Per-stem volume sliders, instant solo to isolate a single instrument, mute to drop the vocals and sing along.
Shape every channel with a 3-band EQ (low / mid / high) and place it anywhere in the stereo field — tuck the bass left, widen the mix.
Every channel draws its own waveform, and the progress bar shows the whole song — tap anywhere to jump straight there.
Move the song into your key without changing the tempo. The vocalist sounds natural, the chords still fit your guitar.
Slow a tricky solo to half speed to learn it — or push the BPM up — without the chipmunk effect.
Drop A → B loops on the toughest section, or bookmark the verse, chorus, and solo to jump straight there.
Every imported song gets its tempo and musical key detected automatically — perfect for setting up a metronome or finding songs in a key.
Stream the mix to AirPlay speakers, AirPods, or your car. Play, pause, and skip from the Lock Screen or Control Center.
Sing, play, or layer harmonies on top of the song. Each take goes on its own track with its own volume slider.
Polish your recordings with reverb, delay, compressor, noise gate, low-cut, and distortion — so your vocals sit naturally in the mix.
Trim the start and end of any recording non-destructively. The kept audio stays locked to the song's timing.
Save individual stems as WAV, or bounce the full mix — or just the looped section — to a single WAV or MP3, ready to share or drop into another DAW.
MonoBand follows your device's appearance automatically, or lock it to Light or Dark whenever you like — straight from Settings.
Use MonoBand in 8 languages — English, Hebrew, Spanish, Chinese, Japanese, German, French, and Portuguese. It follows your device, or switch anytime.
Connect your phone and browse songs, playlists, and favorites right on the car display. One-tap Karaoke mutes the vocals, and the Practice Mix can mute or solo any instrument — simple, drive-safe taps.
MonoBand listens to the song and shows the chords as it plays, synced to the beat — and when you transpose, the chords transpose with you.
MonoBand pulls the melody out of the separated vocal, so any song in your library becomes karaoke. Sing along and watch your pitch land on the note — with a live score, streaks and stars at the end.
MonoBand reads the lyrics off the separated vocal — not the full mix — so they line up with the music as it plays. Fix any word in the built-in editor, and show a translation under each line while you listen. All on your device.
Export the songs you choose — originals, separated channels and recordings — into one ZIP, then import it back on any device. MonoBand shows what's inside before importing and skips songs you already have.
Build playlists, mark favorites, and play whole folders back-to-back with shuffle and repeat. Playback picks up right where you left off — per song.
From "I want to learn this song" to a six-stem session in under a minute.
Bring in audio from Files, the Photos app (videos count too), or record a fresh take.
On-device AI separates the track into 6 instruments. No internet required.
Solo the bass to learn the line. Mute the vocals to sing. Loop the chorus. Slow the solo.
Save the stems, bounce a mix, or share to Messages, Voice Memos, or any DAW.
Every song you import, every stem the AI generates, and every recording you make stays on your device. MonoBand has no servers, no analytics, no third-party SDKs, no account. The AI model runs locally on your device.
